[RFI] RFI via Florescent Lights

[Roger (K8RI)]

To replace 11 2 tube, 8' fixtures would take 22 4' fixtures At $40 each 
= $880, plus the rewiring (all in surface mount conduit) , unless I 
could get 8' LED replacements. If I didn't drop a decimal, at 10,00 
lumens per fixture that's 110,000 Lumens at a current  1650 Watts  (full 
spectrum)   for the shop
The shop well insulated and is heated and air conditioned. It really 
needs both. (programmable thermostat)
